Summary Introduction
Case summary:
The case deals about the store that manufactures old Oregon tables. There are four employees (Person T, Person G, Person L, and Person C) who deal with the operations such as preparation, assembly, finishing, and packaging. Each one would deal with a specific operation. However, all the four are able to do all the four operations. Person R is hired to perform major duties and help when the employees are absent. The time taken by each employee to perform every task is as follows:
Preparation | Assembly | Finishing | Packaging | |
Person T | 100 | 60 | 90 | 25 |
Person G | 80 | 80 | 60 | 10 |
Person L | 110 | 90 | 80 | 10 |
Person C | 120 | 70 | 100 | 25 |
Person R | 110 | 80 | 100 | 10 |
To determine: The fastest way to manufacture the tables using original crew if Person C is moved to either finishing or preparation.

Traditional cast pistons are considered good enough by most engine tuners and builders when it comes to standard setups. They suffer no significant drawback in terms of compression and service life. Performance enthusiasts and custom engine builders prefer the use of forged pistons because they are more durable and easily customised to any configuration, which is essential for engine tuning. Cast pistons are made with the use of large, specialised equipment made up of a mould where the molten aluminium alloy is poured to create the piston shape. Forged pistons employ a single-cast billet of the alloy which is stamped into the required shape using a die. The shape of the die determines the size and shape of the piston. The productivity rates for both methods are different. How do i calculate this?: In this Question, we assume that one unit piston weighs 1.54kg. To calculate the cost per part…arrow_forward
